Arcana Coelestia #9597
9597. 'With cherubs' means the Lord's watchfulness, guarding it from the approach of the hells and the harm they can do. This is clear from the meaning of 'cherubs' as watchfulness and providence, preventing any approach to the Lord except through good and protecting from harm the good from the Lord which exists in heaven and with man, dealt with in 9509, consequently guarding heaven from the approach of the hells and the harm they can do.
Arcana Coelestia #2848
2848. 'Your seed' means spiritual people who, having that good within them that springs from faith, are saved by the Lord's Divine Human. This is clear from the meaning of 'seed' as faith that is the expression of charity, dealt with in 1025, 1447, 1610, 1941, or what amounts to the same, those members of the human race who possess faith that is the expression of charity, that is, who are spiritual people. They are also called by the Lord 'the seed' and 'the sons of the kingdom', in Matthew,
He who sows the good seed is the Son of Man, but the seed are the sons of the kingdom. Matthew 13:37-38.
